Purpose
=======
Always reset the autocomplete value when creating a new tag,
even if the tag already exists.
Technical
=========
The input value is reset when the tag is created because the props
of the autocomplete component change, but if we do not change the props
of the autocomplete component (e.g. because the tag already exist and
nothing should be done), the text value is not reset.
Add a new option for that purpose.
